Totem Custom Pinion Shaft Forged Steel Large Herringbone Gear Shaft¹

Product DescriptionTotem Custom Pinion Shaft Forged Steel Large Herringbone Gear ShaftOur herringbone gear shafts feature zero axial thrust, high torque capacity, and ultra-low noise. Made from 42CrMo alloy steel with carburizing hardening (HRC58-62), followed by precision grinding (DIN 3). Ideal for mining, marine, and turbine applications. Custom modulus (M1-M20) and lengths (up to 6m) available.SpecificationKey ConfigurationsDual Helical Teeth DesignEliminates axial thrust forcesNoise reduction by 15dB compared to spur gearsDeep Carburizing (Case depth 1.2-2.0mm)Surface hardness HRC58-62Core toughness 850-1000MPaProfile GrindingAchieves DIN 3 accuracyRa 0.4μm tooth surface finishApplications1.Marine Propulsion Systems (ISO 6336 certified)2.Mining Crushers (20,000+ hours service life)3.Hydro Turbines (Efficiency ≥98%)4.Steel Rolling Mills (Withstands 5000Nm+ torque)The herringbone gear shaft features a symmetrical double-helical tooth design with a 30° helix angle (adjustable to 15°-45°). The central groove (5-10mm wide) eliminates axial thrust forces, enabling smooth operation under 10,000+ RPM. Teeth are precision-cut with a 20°/25° pressure angle (DIN 5480/ISO 53 standards).Forged from 42CrMo4/34CrNiMo6 alloy steel (EN 10083-3), hardened through carburizing (case depth 1.5mm) or induction hardening (HRC 58-62). Core toughness maintains 850-1000MPa tensile strength. Optional corrosion-resistant coatings: TiN (3μm) or DLC (2μm).Related product recommendationsCustom configurations available upon request.We have different specifications of oil forging presses,ring rolling machines,electric arc furnaces,thus we can provide variety of forging,casting and welding materials according to customer's requests.Large capacity, completed variety of quenching medium: oil,water,salt water,water based mixture.Company ProfileSHANGHAI TOTEM MACHINERY CO., LTD.Shanghai Totem Machinery Co., Ltd.
